BOXING

Mike Tyson told the TODAY Show that he fears for his well-being if he doesn't get help just days after declaring himself a vicious alcoholic on the verge of dying.

"I won't survive if I don't get help," Tyson told Matt Lauer in an interview from Las Vegas.

Tyson said he has been sober 12 days, which includes his declaration at a press conference last week that sounded very much like a plea for help. "I want to change my life, I want to live a different life now," Tyson said last week after discussing a rift with his former trainer. "I want to live my sober life. I don't want to die."

Tyson began his new career as a boxing promoter with his own company, Iron Mike Productions, last week at Turning Stone Resort in midstate New York. The 47-year-old said he has earned, and lost, more than $300 million since he began his heavyweight boxing career 20 years ago.
